Building a Boss

Everything in the Effects section, stitched into one complete boss. This page builds the Toast King step by step: a two-phase boss with a telegraphed AoE, an enrage at half health, minions and rewards.

Step 1: The mob

Start with the body: model, base entity and stats.

# Mobs/toast_king/toast_king.yml
toast_king:
  model: toast
  base: zombie
  display: "&6&lToast King"
  health: 300
  damage: 8
  armor: 10
  scale: 2.0
  persistent: true

/le reload, /le spawn toast_king. It exists, it hits hard, it does nothing interesting yet.

Step 2: An entrance

Spawn and death moments use @world (every player in the world, short for @playersInWorld) so everyone knows what’s happening.

  effects:
  - sound{sound=entity.wither.spawn;volume=2}  +onSpawn @world
  - narrate "&4The Toast King has awakened..." +onSpawn @world
  - narrate "&aThe Toast King has fallen!"     +onDeath @world

Step 3: The signature attack

A telegraphed shockwave as a local effect, driven by a repeat. Warn wide, hit narrow, with a delay between the two.

  effects:
  # ...previous lines...
  - repeat{effect=shockwave;every=3s;for=forever;name=quake} +onSpawn @self
  - stoprepeat{name=quake}                                   +onDeath @self
  shockwave:
  - particlering{particle=flame;radius=5;points=48} @self
  - sound{sound=block.bell.use;volume=2} @playersRadius[20]
  - delay 0.5s
  - particlering{particle=explosion;radius=5;points=24} @self
  - damage{amount=8}   @playersRadius[5]
  - push{velocity=1.2} @playersRadius[5]

Every 3 seconds: flame ring and a bell, half a second to get out, then the blast.

Step 4: The enrage

A phase flip at half health, guarded by a variable so it only fires once. health comes from the condition language.

  effects:
  # ...previous lines...
  - if{cond=health <= 150 && var.phase != 2;then=enrage} +onHurt @self
  enrage:
  - var{phase=2}
  - setname{name=&4&lEnraged Toast King} @self
  - setspeed{amount=0.45} @self
  - glow{glowing=true} @self
  - sound{sound=entity.ender_dragon.growl;volume=2} @playersRadius[30]
  - summon{mob=toast_minion;amount=3;radius=4} @self

Without the var.phase != 2 guard, the enrage would re-fire on every hit below half health, summoning minions forever.

Step 5: The payoff

Reward the killer directly (@trigger on +onDeath is the killer), drop contested loot for everyone else.

  effects:
  # ...previous lines...
  - giveitem{item=diamond;amount=5}        +onDeath @trigger
  - dropitem{item=golden_apple;amount=3}   +onDeath @self
  - lightning                              +onDeath @self

# Mobs/toast_king/toast_king.yml
toast_king:
  model: toast
  base: zombie
  display: "&6&lToast King"
  health: 300
  damage: 8
  armor: 10
  scale: 2.0
  persistent: true
  effects:
  - sound{sound=entity.wither.spawn;volume=2}  +onSpawn @world
  - narrate "&4The Toast King has awakened..." +onSpawn @world
  - repeat{effect=shockwave;every=3s;for=forever;name=quake} +onSpawn @self
  - if{cond=health <= 150 && var.phase != 2;then=enrage} +onHurt @self
  - stoprepeat{name=quake}                     +onDeath @self
  - narrate "&aThe Toast King has fallen!"     +onDeath @world
  - giveitem{item=diamond;amount=5}            +onDeath @trigger
  - dropitem{item=golden_apple;amount=3}       +onDeath @self
  - lightning                                  +onDeath @self
  shockwave:
  - particlering{particle=flame;radius=5;points=48} @self
  - sound{sound=block.bell.use;volume=2} @playersRadius[20]
  - delay 0.5s
  - particlering{particle=explosion;radius=5;points=24} @self
  - damage{amount=8}   @playersRadius[5]
  - push{velocity=1.2} @playersRadius[5]
  enrage:
  - var{phase=2}
  - setname{name=&4&lEnraged Toast King} @self
  - setspeed{amount=0.45} @self
  - glow{glowing=true} @self
  - sound{sound=entity.ender_dragon.growl;volume=2} @playersRadius[30]
  - summon{mob=toast_minion;amount=3;radius=4} @self

One file, one boss, in its own folder beside toast.bbmodel. The only external piece is toast_minion, a second mob for the summons: any simple mob entry works.

Ideas to build on

Make the shockwave faster in phase 2: stop quake in enrage and start a new repeat with every=1.5s.
Add a rare drop with dropitem{items=nether_star 1 0.1} +onDeath @selfLocation: the last number is a 10% chance.
Fire the shockwave on the frame its slam animation lands, with an effect:shockwave keyframe; see Animating Your Model.
Tag the enrage on the line itself instead of a variable: - skill{s=enrage} +onHurt <50% runs only below half health. Add cooldown=9999 (or a var guard) so it fires once. See Line Options.
Give the enrage a particle equation aura so the phase is visible from across the arena.
